Full-Stack Dev — SaaS Infrastructure for Trading App (Supabase + Stripe + Cloudflare) — Fixed Price

MyEdgeOS is a fully functional trading dashboard — 341KB single HTML file, 3,500 lines of vanilla JavaScript, 14 working tabs covering every aspect of a trader’s workflow across 6 asset classes. The frontend is 100% complete. The domain myedgeos.com is secured. The landing page is built. I need the backend infrastructure that turns this into a live, paying, multi-user SaaS. This is infrastructure-only. You will not be redesigning or rewriting the frontend.
